President Mahmud Ahmadinejad unveiled the bomber in a televised ceremony marking National Defense Industry Day. He said that the 4-meter-long unmanned plane, named Karrar or striker in Persian, is intended for deterrence and defensive purposes.

No details were provided on the craft's capabilities. Iran has been producing its own light, unmanned surveillance aircraft since the late 1980s.

Earlier this week, Iran test-fired the new generation of its Qiam-1 surface-to-surface missile, which the Defense Ministry described as a huge step in missile development.
